IMPROVEMENT IN VEHICLE-SPRINGS.

Specification forming part of Letters Patent No. 207,423, dated August27, 1878; application filed November 16, 1877.

To all whom it may concem Be it known that 1, GRANT J UDD, ofStamford,Fairfield county, Connecticut, have invented an Improvement in Gear forExpress and other Wagons; and I do hereby declare the followingto be afull and correct description of the same, reference being had to theaccompanyin g drawings, in which- Figure l is a side view of a wagonhaving my gear. Fig. 2 is a front view of a front axle, showing myinvention. Fig. 3 is a top view of a rear axle. Fig. 4 is a top view ofa front axle, all showing my improved gear. Fig. 5 is a view of a boxinto which the hangers for the springs bear, showing the yieldingcushion and Fig. 6 shows the king-bolt connecting the fifth-wheel.

My invention relates to the gearing of a business, express, or otherplatform wagon, and may also be applied to a pleasure-wagon or even acarriage.

My invent-ion consists in employing two half-elliptic springs, one oneither side of and parallel to the axle, said springs being hung inyielding doublecrank hangers located upon the axle near the hubs, thefifth-wheel resting upon both springs, and provided with a lookingsafety device, which will hereinafter be fully described.

It also consists in applying to the bearings for the springs elasticseats, to modify the jar and jolt of the vehicle in rough places.

In the drawings, A represents the axle, and B B the springs on eitherside of the axle a suitable distance apart. Upon the axles A, near thearms a, are the Babbitt or other metal boxes 0, clipped to the axle bymeans of the double clips 0 or c. The forward clips, 0, are providedwith the shaft jack clips E upon them, thus doing away with thenecessity of any other shaft-clips, and allowing the shaftrubber to beplaced directly under the end of the shaft.

Revolving or rocking in the boxes C are the shafts of the double crankhangers D, upon the outer ends of which are the crank-pins e. Thecrank-hangers D have outside braces strengthening the hanger. Hangingupon the crank-pins e are the ends of the springs B and B, and upon thetop of the center of said springs B and B are bearing-blocks H,

leveling up the spring to admit the fifth-wheel or a cross-bar unitingthe springs.

The front springs support the fifth-wheel x or its equivalent, while theback springs are attached directly to the body of the vehicle.

The fifth-wheel xis constructed in the usual manner, except that upontwo or more sides are lugs y, preventing the wheels from separating, andupon the center of one wheel is a centering-boss, embraced by a collarupon the other, through which the king-bolt passes, so that in case theking-bolt should break, the boss and collar being kept intact by thelugs y, the gear would be kept together, and no accident occur.

In the boxes C are rubber or other elastic cushions z, protected by ametal plate or casing, z, upon the top, upon which the axle of thehangers D rests, and by which the jolting, jar, and noise of themovements of the vehicle are greatly lessened.

The principal advantage, among others, of my invention is that thedouble-crank hangers equalize the pressure upon the two half-springs andgreatly reduce the liability to be broken by a sudden jar or jolt.

Having thus fully described my invention, I claim and desire to secureby Letters Patent-- 1. In combination with two half -springs hung incrank hangers each side of a wagonaxle, afifth-wheel supported upon bothsprings and provided with safety-lugs, substantially as described.

2. The boxes C, forming bearings for the double-crank hangers D D, incombination with the elastic cushion z and protecting-casings z,substantially as described.

3. Two half-elliptic springs of a wagon, hung in crank-hangers D D eachside of the axle of the wagon, in combination with yielding boxessecured upon said axles near the hub, substantially as described.

The above specification of my said invention signed and witnessed, atStamford, Connecticut, this 12th day of November, A. D. 1877.
